How you can figure out the difference?  It's not an easy job to point out the difference even if you're a tennis shop owner.  I dealt with a Chinese seller and was a fake. Here're some tips from my experience you can check.  

1. The bumper and string hole position  : as you can see the picture below, the string hole pattern is different. The fake one (on the right), the space between 4th and 5th hole is narrower than the authentic one.

2. The grommet is different. the material is slightly different. And the color of the fake one is black but the right one has dark (very) gray. The shape is totally different, but if you don't have the authentic AeroPro Drive you may not be able to identify. But, take a look at the second picture you see the bottom-grommet. The fake one is nearly flat but the right one has the three protuberances at the bottom.

3. The cosmetics: Some minor differences in painting. Even a tennis shop staff couldn't find out the difference in 3 minutes. I don't upload the picture since I don't want to let the fake manufacturers know their mistakes. They did a good job, but if you have the authentic AeroPro Drive to compare, take a close look at the logo "aero modular technology" and the logo "a" (stands for "aero") at the CORTEX V-figure parts.

These are the lessons learned through my experience. I wasted 100 box on fake. It took me two days to understand that I was cheated. I sent him these evidence and ask him my money back. A few minutes later the seller deleted his eBay ID so he became a "no longer a registered user" status.

Be aware folks!
